The way you rendered the predator is really cool. It seems impossible to predict, which I guess is accurate for a 2D character avoiding a 3D monster. The game is not fair at all. XD But it's a fascinating premise! Moving around with a grapple is always fun.
Perhaps the 3D creature should cast a shadow? It seems like there should be a hint to help the 2D creature avoid it.
Please put both files into one .zip in the future.
